How does Sun work with Drupal?

Organizers of DrupalCon DC,  in the lead up to the event, asked Sun and the other event sponsors a few questions about their relationship with Drupal.  The first question was:

How does Sun work with Drupal?

I provided this answer:

There are too many ways in which Sun works with Drupal to list them all here, but some of the highlights are:

• In 2005 Sun donated a server to drupal.org when scaling and performance problems were hampering growth
• Then in 2007 Sun donated another server to further propel the scale up of d.o
  
• Sun has used Drupal in building several important online communities:
• • Freshbrain - a technology exploration platform for youth
    
• Plus many organizations run Drupal on Sun technology
• Employees at Sun have been using Drupal internally for lots of things, including:
• • as representative AMP stack environment and workload for lots of benchmarking and performance testing
  • to demonstrate certain technologies, both in Sun internal training, and with Sun's customers, e.g., using the Webstack pre-built bundle of AMP and other open source packages for OpenSolaris, Virtualization with Solaris zones, MySQL installation and tuning, and PHP code analysis with DTrace.
    
• Sun has created a NetBeans plugin wizard for developing Drupal modules
• Sun is currently investigating system appliances for data archive and CMS that would bundle Drupal
• Of course, Sun is a large contributor to some of Drupal's most critical underlying open source technologies:
• and let's not forget that Sun VP and inventor of Java, James Gosling, defended Drupal inventor Dries Buytart in his PhD examination at Ghent.
  

Clearly, Sun is deeply connected to the Drupal community in many ways.

All the Q&A from DrupalCon's sponsors will be posted here on the DrupalConDC site.

\* Entry corrected to say Sun has contributed more FLOSS code than any other single institution, not Sun has contributed more code to the Linux kernel than any other single institution (although I think I did read that somewhere, it's not substantiated in this paper).  Thanks to Matt for point that out - it's major difference.
